OpenLog is an open source data logger. Simple to use, simple to change. We wanted to create a serial logger that just worked. Power this device up and it will start logging any received serial data at 9600bps. Sending Ctrl+z will drop out of logging and in to command mode. 'new' will create a new file. 'md' makes a directory. '?' brings up the list of commands. OpenLog doesn't do a lot, but it does log serial streams extremely well. Example:

>new testfile.txt>append testfile.txt

That's really it! OpenLog firmware is open source and is based on Roland Riegel's FAT library. OpenLog currently supports FAT16 (upto 2GB microSD cards). We're working on FAT32 and would love your help!

All the design files (schematic, PCB layout, firmware) are open source released under the CC-SA v3 license and are available through Github.

Features

Log to low-cost microSD cards up to 2GB

Simple command interface

Three modes:

NewLog creates a new log every power up and immediately starts logging

SeqLog appends a file called "SeqLog.txt" at every power up and immediately starts logging
